The first thing you need to do is make sure you have enough paint for the ceiling, walls and woodwork. A standard size living room, in a 3 bed semi detached house for example, will need about 5 liters of ceiling paint, 5 liters of wall paint and between 1 liter to 2.5 liters of woodwork paint. This is assuming 2 coats of paint throughout. If you think its going to take more than 2 coats of paint then you might need to up the quantity a bit.
You might also need some wall filler (polyfilla/Toupret) for any holes in the walls or ceiling and you will need a tube of caulk for any gaps or cracks where woodwork meets the wall.
You will need to make sure have all the right tools too. You will need these following tools:
Paint sheets and some plastic for covering furniture.
Paint brushes for walls and woodwork.
Paint rollers & rolling pole.
Paint tray or paint scuttle.
Filling knives & caulk gun
Masking tape & low tack masking tape.
Wallpaper steamer (if removing wallpaper).
Before you start painting your walls etc you will need to make sure they are clean, if you use a damp cloth and give a section of the wall a good rub down you will be able to tell if there’s grime that needs to be removed. If grimy then use sugar soap or a product called KrudKutter to clean down the surface. Painting is all about preparation, if the surface is dirty then painting over it is going to guarantee a bad finish!
If Removing old wallpaper then its best to use a steamer. Working from the top of the wall down remove the paper in sections. Once all the wallpaper has been removed you will need to scrub the walls to remove the old glue. You can pick up a product to help with this from a paint shop like Stillorgan Decor.
Assuming the ceiling, walls and woodwork have been prepared and cleaned then the first step in how to paint a room is to move furniture to the middle of the room. Then take down pictures from the walls, take down curtains etc. Put everything in the middle of the room and cover with your plastic sheets. Tape the plastic into position with the masking tape.
Now starting with your ceiling paint, using a 3 inch emulsion paint brush, paint all around the edges of the ceiling. The area of ceiling that meets the walls, also paint around any light fittings.
Once this is done you can paint the rest of the ceiling using your paint roller. When rolling the ceiling with the paint roller make sure to start close to a light source like a window and work back into the room. Theres a good reason for this, if you work away from the light its easy to see where you are and if there’s any misses. If you work towards the light then its going to be a lot harder to see where you are going and whats been done. I know this sounds obvious but you would be surpised by the amount of people that paint the ceiling towards the light and the wonder why there’s so many misses afterwards!
Once the ceiling has been finished you can move onto sanding down the woodwork and then painting the walls. Theres a couple of ways you can go from here. Usually we would undercoat the walls and woodwork first, then finish the walls and finally finish the woodwork. A professional & experienced painter will be able to paint a nice straight line between the walls and the woodwork. If you don’t feel confident enough to do this then there is another option.
Instead of finishing the walls first you can bring them up to a finish, just don’t apply the final coat. Next paint your woodwork, its best to carry out any filling in between coats then touch up the filler and apply the finish coat. By now you should have some nicely painted woodwork. Leave the woodwork alone until its good and dry, over night at least. Next, using a low tack painters tape, tape along the tops of the skirting boards and down the sides of the architraves etc. Make sure the tape is stuck well. When this is done crack on and paint the walls, the same way you would paint the ceiling. Use the paintbrush and go around all the edges first and make sure to paint around sockets etc. This paint work is called cutting in, once everything has been cut in you can roll out the walls. If the paint looks good and solid then you can peel back the low tack masking tape to reveal laser sharp lines between walls and woodwork!
